The curriculum at our institution provides a foundation for the traditional chemistry degree and a fundamental physical science background for students in a wide array of majors. This work focuses on increasing student exposure to modern analytical instrumentation via the quantitative analysis laboratory, an entry-level course in applied chemistry for non-chemistry scientists, and through outreach activities involving students in grades 4-12. Using experiments in gas chromatography (GC) and atomic absorption spectrophotometry (AAS), students gain experience in hands-on instrument operation and data analysis. Experiments are designed as problem based or discovery investigations into applications students encounter, based on their academic interests. As modern instrumental methods are introduced, fundamental analytical principals are continually stressed. Of particular interest is the exposure of pre-service teachers to modern analytical instrumentation. This exposure enhances their ability to answer complex questions from students in discussing current events in which chemical analyses are reported. Additional benefits for chemistry majors occurs in subsequent semesters when students undertake senior-level research projects. Non-chemistry majors gain experience that allows them to evaluate and make decisions based on the interpretation of analytical data. Integration of experiments demonstrating the contributions of female scientists is used to enhance the learning experiences for all students.

我们机构的课程为传统化学学位奠定了基础，并为各种专业的学生提供了基本的物理科学背景。 这项工作的重点是通过定量分析实验室增加学生接触现代分析仪器，这是非化学科学家应用化学的入门课程，并通过涉及4-12年级学生的外联活动。 通过气相色谱（GC）和原子吸收分光光度法（AAS）的实验，学生可以获得动手操作仪器和数据分析的经验。实验设计为基于问题或发现调查学生遇到的应用程序，根据他们的学术兴趣。 随着现代仪器方法的引入，基本的分析原理不断得到强调。 特别感兴趣的是暴露的职前教师现代分析仪器。 这种接触提高了他们回答学生在讨论报道化学分析的时事时提出的复杂问题的能力。 化学专业的额外好处发生在随后的学期，当学生进行高级研究项目。 非化学专业的学生获得的经验，使他们能够评估和分析数据的解释的基础上作出决定。 综合展示女科学家贡献的实验，以加强所有学生的学习经验。
